A stud 11 and a positioning post 12 are fixedly installed on the top of the protective frame 1 between two adjacent anchor bolts 5. A protective net 2 is pressed and fixed to the top of the protective frame 1 by a pressure frame 3. A limiting plate 21 is fixedly installed at the edge of the protective net 2. Positioning holes 22 are provided on the limiting plate 21, with each limiting plate 21 having equally spaced, parallel positioning holes 22. Several studs 11 and positioning pins 12 are connected to the positioning holes 22. The pressure frame 3 is pressed and fixed on the limiting plate 21 by nuts 4. The pressure frame 3 has through holes 31 that mate with the studs 11. The upper end of the stud 11 passes through the through hole 31 and is threaded to the nut 4. By aligning the positioning holes 22 on the limiting plate 21 at the edge of the protective net 2 with the studs 11 and positioning pins 12 on the top of the protective frame 1, and by making the studs 11 and positioning pins 12 pass through the corresponding positioning holes 22, the limiting plate 21 is placed on the protective net 2. Next, align the through hole 31 on the top of frame 1 with the stud 11 on the top of the protective frame 1, and let the stud 11 pass through the through hole 31, so that the pressure frame 3 presses onto the limiting plate 21. Finally, by screwing the nut 4 onto the upper end of the stud 11, the pressure frame 3 is pressed and fixed by the nut 4, thus completing the fixing of the protective net 2. It eliminates the need for fixing with multiple clamps, making the operation more convenient and improving the installation efficiency of the protective net 2. When fixing the slope protection structure, the protective frame can be fixed by fixing the anchor rod 5. 1. Fix the protective net 2 at a suitable position on the slope. Then, align the positioning holes 22 on the protective net 2 with the studs 11 and 12, so that the studs 11 and 12 pass through the corresponding positioning holes 22. Place the limiting plate 21 on top of the protective frame 1. Next, align the through hole 31 on the pressure frame 3 with the studs 11, so that the studs 11 pass through the through hole 31.
